Abstract
The purpose of this study is to analyze the learning trajectory that can help students understand the concept of volume cubes and beams with filling and arrangement boxes using dice context in grade VIII of junior high school (SMP). This research is a design research type of validation study that is implemented through Realistic Mathematics Education (RME). Design research is carried out in three stages, namely: preliminary design, teaching experiment consisting of cycle one and cycle 2, and retrospective analysis. The study was conducted in grade VIII of SMP at Tangerang City. The results of the study show that students can understand the volume of cubes and beams through progressive mathematical identified at the situational stage, recognizing the volume unit with the arrangement of unit cubes; referential stage, calculates the number of unit cubes that can be made on cubes and beams; general stage, found the capacity of objects in the form of cubes or beams based on known ribs and blocks; formally stage, calculate the volume of cubes and beams if the ribs are known.
